To all whom it mag concern.-

Be it known that I, MATHIAS JENSEN, of Astoria, in the county of Clatsop and State I ot' Oregon, have invented a new and improved -Machine for Soldering Sheet-Metal Caning sheet-metal can-bodies, such as shown and described. in theapplicatiou for Letters Patent, SerialNo. 331,011, filed by me Novem- 7 her 20, 1889.

x 5 The object of the invention is to-provide a new and improved machine for soldering sheet-metal can-bodies, and by which the solder isprevented from entering theinsides of the bodies during the process of soldering,

- so as to prevent spoiling or poisoning the goods packed inthe finished cans and save solder. 1 v The invention consists of adevice for bending the ends of the seam of each can-body in- I 2 5 ward preparatory to fiuxing and soldering it,

' and itfnrtherconsists of adevice forstraightening the seam after it is soldered and wiped.

The invention also consists of certain parts and details and combinations of the same, as

. will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

The soldering-machine A, presently to be described, is preferably used in place of the soldering device in the machine for forming sheet-metal can-bodies shown and described in application for Letters Patent, Serial No. 331,011, above referred to. The sheet-metal 6c blank is preferably formed into acylindrical body with interlocked lips by the several devices shown' and described inthe said applica tion, and then the body so formed passes from the horn B onto the carrying-frame C of the soldoring-machineA by a reciprocating mechanism D, operated-from the main driving-shaft E, as more fully described in the application above referred to. A second device F, also described in the above-mentioned applica- 7o tion and operated from the transverse main driving-shaft E, serves to impart an intermittent motion to the several can-bodies on the carrying-frame O.

The front end of the carrying-frame C is pivotally connected with the end of the horn B, and the rear end of the said carrying-frame carries the roller 0, adapted to rest on a roller 0 mounted to turn in suitable bearings on the outer end of the bracket of the main frame O, on which the soldering-machine is mounted, the said main frame being part of the main frame for the machine for forming sheet metal can-bodies .described in the application above referred to. 8

The soldering-machine A is provided with afluxing device H, arranged on the under side of the carrying-frame C and located alongside the soldering device I, both devices H and I being of the same construction as those de- 0 scribed in the application, Serial No. 331,011,

above referred to, so that a further detailed description of the same is not deemed necessary. Between the fluxing device H and the end of the horn B is arranged a bending device J, for bending the ends of the seam of the can-body inward, as illustrated in Fig. 10, preparatory to the passing of the said can-body into the fiuxing device H andthe soldering deviceJ. In the rear of the latter is arranged a straightening device K, which serves to straighten out the bent ends of the seam after the can-body has left the soldering device I. The saidbending device J and the straightening device K are constructed as follows: Both devices are operated simultaneously from the main driving-shaft E, which for this purpose is provided with a bevel gearwheel E, meshing into abevel gear-wheel E, secured on the longitudinally-extending shaft E, mounted to turn in suitable hearings on the main frame G. A pulley E is secured on the shaft E, and over it passes a belt-E ,.also passing over a pulley E, secured on the longitudinally-extending shaft L, mounted to turn in suitable hearings in the lower part of the main frame G and carrying on its outer end a pulley L, over which passes the quarter-twist belt L also passing over a pulley L secured on a shaft L, extending transversely and mounted to turn in suitable bearings on the outer bracket of the main frame Gin line with the straightening device K. (See Fig. 9.) On the shaft L is secured a gear-wheel L, which meshes into agear-wheel L secured on the shaft L carrying the wiper L which serves to wipe the seam of the can-body before it passes to the straightening device K. The shaft L is mounted to turn. in aframe L, fulcrumed on the shaft L and counterbalanced by a weight, so as to press the wiper L in contact with the under side of the seam of the can-body.

On the shaft E, previously mentioned, is arranged a cam-wheel N, on the periphery of which travels a friction-wheel N, mounted to turn in a plate N held vertically adjustable -on a lever N fulcrumed at N to the main frame G, the said plate being secured in place when adjusted by a set-screw'N (See Figs. 2 and 3.) On the lever N is formed a longitudinally-extending arm N on the top of which is secured the male die J of the bending device J, the said die being secured in place on the arm N by suitable set-screws N as is plainly shown in Figs. 3 and 4. The

male die J. is provided on its top with a concave recess J the ends of which are curved upward at J as is plainly illustrated in Fig. 3. Over this concave recess is adapted to opcrate the female die J similarin shape to the recess J 2 and supported on the links J extending vertically and pivoted on a cross-plate J secured between the sides of the carryingframe 0. A spring J 7 is secured by one end to the carrying-frame G and by its other end to one of the links J so as to hold thelatter,

vends of the die.

body 0 under treatment when in the bending mechanism J. The female die J, as well as the recess J in the male die J, is of the same length as the can-body, so that when the latter is between the said dies and the lever N is swung upward. the said male die J presses against the under side of the can-body and the latter against the female die J, so that the ends of the can-body are bent inward by the curved ends J a of the said recess and female die. The can-body 0 then assumes the shape shown in Fig. 10. It is understood that the seams O of the can-bodies passing .along'the carrying-frame are always on theunder side.

When the shaft E is rotated from the main driving-shaft E, the cam N, acting on the friction-wheel N, causes the lever N to swing upward, so as to impart the necessary upward motion for bending the can-body to the said male die J When the highest point of the camN has passed the friction-wheel'N, the

. lever N swings downward by its own weight until the friction-wheel N stands at the lowermost point of the said cam, as is'plainly shown in Fig. 2. Now, in order to operate the straightening mechanism K simultaneously with the bending mechanism J the said lever N is provided with an arm N pivotally connected by a link N with an arm P, secured on a longitudinally-extending.

. the outer end of the said shaftP is secured an arm P pivotally connected by a link P with a lever P, fulcrumed on the top and on the outer bracket of the, main frame G in line with the shaft L, previously described. The lever P extends inward and overthe carrying-frame G, and is provided at its inner end with adjustable bolts Pfi-adapted to operate. the male die K of the straightening frame G, the upper endsbeing-adapted to beengaged by the bolts P held on the lever P.

The distance between the ends K of the male die K is equal to the length of the can-body under treatment, so that when the can-body is in place on the male die, as plainly illustrated in Fig. 7, and the lever P descends, then the lower ends of the bolts Pcan press onto the ends of the said male die without striking the can-body resting between the The male die K is held on p a bolt K, secured to its bottom and extending upward through a transverse plate K secured to the sides of the carrying-frame G. A spring K is coiled on the upper end of the bolt K and is secured by one end to the said bolt and rests atits other end on the top of the plate K so that when the die is pressed downward by thebolts I thespringK is compressed and drawsthe die upward to its normal position when the lever P swings upward. The female die h is concave on its surface, and the under side of the male die is correspondingly shaped, and is also provided with a longitudinally-extending groove K for the reception of the inside of the seam.

The can-body O is moved into the proper position on the male die K from'the reciprocating device F, which is provided atits rear end with longitudinally-extendiug arms F and F passing to the sides of the carryingframe 0 and provided with lugs F, which engage the inner edges of the can-bodies, so that'when the device F is reciprocated and is on its outward stroke the extreme outer ends of the said arms engage the can-body on the die K and shove the can-body off of the latter and over and between the rollers C and 0 from which they drop into a suitable receptacle. At the same time the lugs F move a new can-body onto the die K to the position shown in Fig. 7.

In order to prevent the can-bodies from turning between the bending device J and the straightening device K, the insides of the sidesof the carrying-frame O are provided with longitudinally-extending strips C adapted to pass at their inner edges onto the straight part of the bent ends of the can-body, as is plainly shown in Fig. 8, whereby a turning of the can-body is prevented.

The operation is as follows: W hen themain driving-shaft E is set in motion, the several can-bodies receive an intermittent forward motion on the carrying-frame C by the reciprocating device F. The can-body, after leaving the horn 13, is passed between the dies J and J" of the bending device J, and as soon as the reciprocating device F is on its returnstroke and the several can-bodies on the carrying-frame O are at rest then the cam N swings the lever N upward,so that the male die J bends the ends of the can 0 into the shape shown in Fig-10. As soon as this has been accomplished the lever N swings downward, and then the reciprocating device F moves the bent can-body forward onto the fluxing device II, in which the acid is passed into the seam or only on the outside, as the bent upper ends 0' of the said can-body O prevent the acid from passing to the inside. After this is accomplished, at the next forward stroke of the reciprocating device F the bent and fluxed can-body Q is passed onto the soldering device I, in which the solder is passed onto the outside'of the seam only, as the bent upper ends 0' of the said can-body prevent the solder from passing to the inside of the can as long as the latter is held with its under side on top of the solder bath. At the next forward stroke of the reciprocating device F the soldered can-body passes to an intermediate position between the soldering device I and the straightening device K, and at the next following forward stroke of the as the lover I swings upward the spring K raises the male die K to its former position, and the next following forward stroke of the reeiprocatin g device F moves the straightened and soldered can-body 0d of the machine. It is understood that as the male die J of the bending device J moved upward and presses against the under side of the can-body the lover I swings downward at the same time, so that an equal pressure is exerted on the top and bottom of the carrying-frame (J to prevent the latter from being raised, which would be the case if the lever I did not swing downward at the same time that the lever N swings upward.

Having thus fully described my invention, I claim as new and desire to-s'eeure by Letters Patent 1.
